Memory spec terms
If you're not sure if a module is right for your system, use Memory America configurator for a list of guaranteed compatible modules.

NON-ECC/Non-parity — Most desktop and laptop computers take NON-ECC or Non-parity memory.

ECC/Parity — ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses.

Unbuffered — Most PCs and workstations use unbuffered memory which is faster than registered memory.

Registered/Buffered — Registered or buffered modules delay all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.

Fully buffered — Designed for next-generation servers, features an advanced memory buffer.

CL — CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL.

For a return for credit, this item must be returned to Memory America within 30 days of the invoice date for this policy to apply. For a replacement, we offer a Lifetime warranty and support on all memory upgrades. “Return” constitutes receipt of the product by Memory America, and not the mere issuance of an RMA.

The following conditions are not acceptable for return, and will result in the merchandise you have returned to Memory America being returned to you:

Modules exhibiting physical damage

Modules that are missing the manufacturer label containing model number, part number or serial number

Modules that are missing the manufacturer warranty label

Will ecc memory work on a non ecc motherboard?

ECC Memory has an extra chip on the memory that performs Error Checking and Correcting functions. It's really only recommended for machines being used as servers.
For home systems, non-ECC memory is recommended unless you KNOW you need the ECC function. This is because ECC and non-ECC memory can almost always be mixed in the same system with no problems. If you mix these types of memory, the system will run as if all the memory was non-ECC.
Non-ECC memory is also recommended because it runs a little faster than ECC memory since it doesn't need to do the extra error checking. ECC memory is only really beneficial if you're going to be processing massive amounts of data (like a server does) and all data needs to be 100% accurate. Non-ECC is all that's needed for 99% of the computers out there.

What is registered memory?

A memory module that contains registers that hold the data for one clock cycle before it is moved on to the motherboard. This process increases the reliability of high-speed data access. Registered memory modules are typically used only in servers and other mission-critical systems where it is extremely important that the data is properly handled.
